MARCI weather report, Jan 30-Feb 5, 2017

Continued local-scale dust storm activity across many regions of the northern hemisphere of Mars this past week. The Acidalia storm-track was active with short-lived dust storms on most afternoons. Looking towards the other northern lowlands, Amazonis, Utopia, and eastern Elysium were also busy with small dust storms. The north polar hood has started to reveal some ground frost on a number of crater walls and rims where the atmospheric feature was less optically thick. The southern highlands continued to be relatively uneventful by comparison. Dust clouds and hazes from Acidalia storm-track activity were observed near Argyre and over western Noachis Terra.
